Damsons are small, ovoid, plum-like fruit with a distinctive, somewhat astringent taste, and are widely used for culinary purposes, particularly in fruit preserves and jams. In South and Southeast Asia, the term damson plum sometimes refers to jamblang, the fruit from a tree in the family Myrtaceae. [4]
This is a list of some of the more commonly known problems that are NP-complete when expressed as decision problems. As there are thousands of such problems known, this list is in no way comprehensive. Many problems of this type can be found in Garey & Johnson (1979).
The problem to determine all positive integers such that the concatenation of and in base uses at most distinct characters for and fixed [citation needed] and many other problems in the coding theory are also the unsolved problems in mathematics.
The real part of every nontrivial zero of the Riemann zeta function is 1/2. The Riemann hypothesis is that all nontrivial zeros of the analytical continuation of the Riemann zeta function have a real part of 1 / 2 . A proof or disproof of this would have far-reaching implications in number theory, especially for the distribution of prime ...
Damassine owes its distinctive taste and aroma to the region's limestone soil and climate [2] . The aromas are very complex and are composed of a variety of ingredients . The scents of wild plum are dominant, while herbal and bitter almond notes are always present.
For functions in certain classes, the problem of determining: whether two functions are equal, known as the zero-equivalence problem (see Richardson's theorem); [5] the zeroes of a function; whether the indefinite integral of a function is also in the class. [6] Of course, some subclasses of these problems are decidable.
Function problems can be reduced much like decision problems: Given function problems and we say that reduces to if there exists polynomially-time computable functions and such that for all instances of and possible solutions of , it holds that
A classic example of a pathology is the Weierstrass function, a function that is continuous everywhere but differentiable nowhere. [1] The sum of a differentiable function and the Weierstrass function is again continuous but nowhere differentiable; so there are at least as many such functions as differentiable functions.
